Hydroxy terminated polybutadienes

ABSTRACT

A HYDROXY-TERMINATED POLYBUTADIENE IS FORMED BY REACTION WITH A CARBOXY-TERMINATED POLYBUTADIENE AND AN ALKYLENE OXIDE. THE HYDROXY POLYMER HAS APPLICATION FOR USE AS A BINDER FOR SOLID PROPELLANTS WHEN CURED WITH A TRIISOCYANATE OR A DIISOCYANATE AND A TRIS ( HYDROXY-TERMINATED) POLYHYDROCARBON.
